Saad Shaikh

• Performed further tests at UCL with DDC232 in plastic PELI case in D109 and D27.
  • Plastic housing appears to significantly improve shielding from external electronic noise.
  • Two runs appended to Nov 27 dataset.
• Tested frame rate of live ROOT fit with and without graph display: 12Hz without display, 5.5Hz with (canvas size dependent).
  • Will start working on framework to capture data, average and perform fit and then upload results to web server.
• Nexys Video boards have been modified to allow separation of JTAG programming and DPTI interface. Can now use libFTDI for data transfer and see signals with ILA.
  • Will get back to debugging USB interface.
• Now able to configure Nexys Video via SD card without Vivado, using 200GB SD card Fern provided.
• New DDC232 board prototypes due to arrive on Friday 18th, will collect and test after Christmas break.

Fern Pannell

• Chart.js is intended as the JavaScript library with which to generate the final display
  • Slicker aesthetics than HTML Canvas and CanvasJS
  • Commercial licensing more appropriate
• CanvasJS will be used for the intermediate development stage
  • Moving away from the current HTML Canvas prototype towards a Chart.js model, via a CanvasJS interim product
  • Substantial documentation and online support with CanvasJS compared to Chart.js, making the transition easier
  • Subtle differences (so far) between CanvasJS and Chart.js, suggesting the move between these two libraries will be relatively straightforward.
• Current goals of the display visualised in CanvasJS
  • Dynamically updating bars with a "fitted Bragg Curve" on top of the bars
  • Randomly generated (hardcoded, not file-read) values currently, just to be able to create a quick visual
  • HTML Canvas issues such as axis labelling and adjusting scales have been removed with this CanvasJS version
• Next Steps:
  • Get the CanvasJS model to display the data outputted from the Java file
  • Once successfully displaying the java-written values, test the display with Saad and the Photodiodes - check the display is behaving as expected (important: y-axis should remain static)
